The Nobel Assembly at Karolinska Institutet has today decided to award
the 2017 Nobel Prize in Physiology or Medicine
Jeffrey C. Hall, Michael Rosbash and Michael W. Young
for their discoveries of molecular mechanisms controlling the circadian rhythm
Life on Earth is adapted to the rotation of our planet. For many years we have known that living organisms, including humans, have an internal, biological clock that helps them anticipate and adapt to the regular rhythm of the day. But how does this clock actually work? Jeffrey C. Hall, Michael Rosbash and Michael W. Young were able to peek inside our biological clock and elucidate its inner workings. Their discoveries explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth’s revolutions.
